Lukka, Bound to Ruin

Compleated turns this walker's arrival into a wager settled before it ever hits the battlefield: pay the hybrid pip with red or green mana and land at a full five loyalty, or pay two life and arrive at three. That two-loyalty gap is the whole decision, because five is exactly enough to fire the minus-four sweep the turn it enters, while three keeps you off it, forcing a turn of plus-one first before the ultimate comes online. Either way, every mode feeds the same engine. The plus-one is not generic ramp; it makes red-green mana that can only be spent on creature spells or the abilities of creatures, which locks the walker into a creature-centric build rather than a value-goodstuff one. The minus-one manufactures a 3/3 with toxic, both a blocker and a body that raises the ceiling of the ultimate. And that ultimate is the payoff: it deals damage equal to the greatest power among your creatures, divided as you choose, so the token you have been making, or anything larger, becomes a spear you point at any creatures or planeswalkers where it hurts. The loyalty economy runs in one loop: the plus-one enables the creatures, the creatures fuel the minus-four, and compleated lets an aggressive deck spend life it expects not to need to skip the ramp step entirely. What sets this apart from most planeswalkers is how sealed that circuit is; nothing here reaches outside the board it is already building.
